108 MetaFrame Solutions Guide

machine that uses the domain controller to be authenticated using the SecurID

solution.

Any machine, whether local or domain, on which you want to use SecurID

authentication must have the ACE/Agent installed.

Two example configurations are shown below:

Example 1

An ICA Client, using RAS, connects to the MetaFrame server Server_1 in the

domain DC_EX and the user specified is a member of DC_EX’s domain

Sdremote user group. The user is challenged with the SecurID authentication.

In this example, both Server_1 and DC_EX must have the ACE/Agent

installed.

Example 2

An ICA Client, using ICA remote control, connects to the MetaFrame server

named Server_2 and logs into domain DC_EX2. The user is a member of

DC_EX2’s domain Sdlocal group. The user is challenged with the secondary

authentication.

Both Server_2 and DC_EX2 must have the ACE/Agent installed.

Troubleshooting

When I try to connect to the MetaFrame server using RAS, it drops the connection

whenever it tries to verify the username and password on the network.

Do not forget to turn on the terminal mode after dialin option on the RAS client

side. This option is essential or you will not be prompted by the SecurID

authentication.

When I try to log on to the MetaFrame

server using a RAS or session connection,

I get a “User access denied” message. The ACE/Server log shows the message

“Node verification failed.”

There are two possible causes. First, check to see if the client configuration on the

ACE/Server has the Sent Node Secret box checked. If it does, uncheck it. Next,

on the MetaFrame server, look in the %SystemRoot%\System32 directory. If the

file Securid exists, delete it. Try to log on again. If you still get the failure, delete

the Sdconf.rec file from the %SystemRoot%\System32 directory and obtain a

current copy from Security Dynamics.
